COMMENTS

These diagnostics are enabled either by the customer or the OEM and are not enabled on most chassis.

The EECU will broadcast this fault on the J1587 line if engine speed from one or more sensors exceeds 2500 RPM. This is a plausibility check.

In Step 6 the SID was accidentally set to SID 32. It should be SID 152 which was fixed in Step 7.

The EECU will log this fault if both J1587 and J1939 communications with the VECU have been lost. Under these circumstances the engine will shutdown.

The EECU logs this fault if it has detected an internal problem.

The EECU will log this fault if it has been instructed by the VECU to perform its post-run diagnostics and stop operation, and the EECU finds that the electrical power has not been shut off by the VECU.

Code 7-5 is sent by the VECU based on battery/alternator voltage.

If the EECU determines that its own internal voltage is below a plausible limit but the EECU continues to run then this fault is logged (ex. If the voltage is 4 volts the microprocessor could not run. If the processor is running then there must be an internal problem). The EECU uses this voltage value for solenoid control. If the voltage measurement is incorrect poor engine performance can result. If this code is accompanied by a 7-5 code then there is an external voltage problem.

MID 128, PID 190, FMI 2

For older software levels the EECU will log this fault but not broadcast it on the J1587 line if engine speed from one or more sensors exceeds 2500 rpm. This is a plausibility check without a blink code. New software versions will broadcast this fault with a corresponding blink code.

MID 128, SID 151

The EECU is having a problem controlling certain portions of the solenoid current but a more exact diagnosis can not be made by the EECU. Contact Service Engineering.
